Measurements of activity coefficients at infinite dilution for organic solutes and water in the ionic liquid 1-butyl-1-methylpyrrolidinium tricyanomethanide

Surface tension and 0.1MPa density for members of homologous series of ionic liquids composed of imidazolium-, pyridinium-, and pyrrolidinium-based cations and of cyano-groups containing anions

“…Therein lies the additional value of the presented 80 new buoyancy data points for 0.1 MPa density for the four studied tricyanomethanide ionic liquids. The agreement of the present densities for 1-butyl-1-methylpyrrolidinium tricyanomethanide with the vibrating tube data by Domańska et al [20]- [22] within ±0.04 %, even though the data were obtained by different methods, confirms reliability of the data from both data sets being compared. Though the present study has multiplied the available data on the surface tension of the studied ionic liquids, they remain scarce and the research on the surface tension of tricyanomethanide ionic liquids is only M a n u s c r i p t at its very beginning.…”

“…Among the properties of the four ionic liquids, the density of [C 2 MIM][TCM] [1], [11]- [17] and of [C 4 MIM][TCM] [12], [15], [16], [18], [19] and [25] have been most studied. For [C 4 MPYR][TCM], 18 data points in temperature range from (298 to 363) K have been published by Domańska et al [20]- [22]. Lukoshko et al [25] reported 6 data points for [C 4 MPY][TCM] in the temperature interval (293 to 343) K.…”

Thermochemical investigations of solute transfer into ionic liquid solvents: updated Abraham model equation coefficients for solute activity coefficient and partition coefficient predictions

“…[24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] The ion-specific equation coefficients can be combined to allow one to predict solute [40], were used to derive Abraham model log K and log P correlations at 298 K and 323 K. As part of the present study we have also updated the cation-specific and anion-specific equation coefficients published in our earlier papers. The last major revision of the numerical values of the coefficients occurred slightly more than three years ago and was based on a total of 1790 log K and 1760 log P values.…”

Measurement of Activity Coefficients at Infinite Dilution for Alcohols in [BMIM][CH3SO4] using HS-SPME/GC-FID

“…New methods using ILs have been proposed for extraction, extractive distillation, and separation (Domanska and Lukoshko, 2013). These solvents are described in the literature as bulky organic cations with low symmetry (Greaves and Drummond, 2008); imidazolium and pyridinium are the main cations (Dobryakov and Maurer, 2008) and the main anions are usually polyatomic and inorganic such as CH 3 SO 4 -and BF4- (Huang et al, 2008).…”
